• User registration and login system.
• Authentication using JSON Web Tokens (JWT).
• Navigation between screens and logout functionality.
• Displays "Home Screen" after successful login.
• Persistent authentication state using local storage.

• @react-native-async-storage/async-storage: AsyncStorage module.
• @react-navigation/native and @react-navigation/native-stack: React Navigation library.
• axios: HTTP client.
• expo: Expo SDK.
• react: React library.
• react-native: React Native framework.
• react-native-safe-area-context and react-native-screens: React Native helper libraries.

• Open the app and navigate to the "Sign Up" screen.
• Enter your email and password to create a new account.
• Click the "Sign Up" button. If the registration is successful, you will be automatically logged in and redirected to the Home screen.

• If you already have an account, navigate to the "Login" screen.
• Enter your email and password.
• Click the "Login" button. Upon successful authentication, you will be redirected to the Home screen.

• After logging in, you can log out by pressing the "Logout" button in the Home screen’s header.

• The app stores the authentication token in AsyncStorage to maintain the user's session even after the app is closed and reopened.
• Upon launching, the app checks for a stored token and updates the authentication state accordingly.
